CLEANING DEVICE FOR CARBOYS.

Specification of Letters Patent.

Patented Jan. 24., 1911.

To all whom it may concern:

Be it known that I, ALFRED J. BERG, a citizen of the United States,residing at Kittery, in the county of York and State of Maine, haveinvented new and useful Improvements in Cleaning Devices for Carboys, ofwhich the following is a specification.

This invention relates to bottle cleaners and particularly to cleanersadapted for use in carboys.

The object of the invention is the provision of a simple, cheap andefficient device which when in collapsed position will freely enter theneck of the bottle and can be expanded so as to bring its cleaningbristles in engagement with the bottom, sides and top of the bottle sothat every portion of its inner surface is properly cleansed.

A still further object of the invention is to provide a device of thischaracter which may be conveniently applied to a bottle and rotatedtherein and whereby the parts may be interchanged for repairs.

In the drawing :-Figure 1 is a sectional view of a bottle showing thedevice applied. Fig. 2 is an elevation showing the device collapsedandready for entrance into the neck of the body. Fig. 3 is a section on theline 3-3 of Fig. 1 showing the device expanded and removed from thebottle. Fig.- .4 1s a similar section 011 the line 4- .1: of 1* 1g.

1. Fig. 5 is a detail sectional vicw'of the supporting head.

Referring more especially tothe drawing 1 represents the driving shaftwhich has secured to its lower end a head 2 forming arings for thebottom arms 3 of which there may be any suitable number. The arms 3 arehinged to the head so that when collapsed are adapted to lie parallel tothe shaft 1 and have hinged to their outer ends the vertical or sidemembers. 4 which are hinged at. their opposite ends to the flexible topmembers 5 and these in turn are hinged at their opposite ends to thehead 6 of the slidin sleeve 7 Each of the bottom members an each of theside members comprise wooden strips apertured at 8 throughout theirlength to receive the bristles 9 thereby forming the brush. The bristlesbn the side members and bottom members are made of varying lengths asshown at a, b, and a in order that they may enter the crevices orcorn'ers of the bottle. The upper flexible members 5 areconstructed of astrip of spring steel or any other suitable material and have stretchedthereover a canvas covering 10 in which is secured the bristles 11.These members are slightly bowed so as to conform to the curved headofthe bottle and are adapted to collapse substantially parallel with theshaft 1 when the device is inserted in the neck 12 of the bottle.

The shaftl is provided with a longitudinal key-way 13 in which a key 11is adapted to move, said key passing through a collar in the sleeve 7;Surrounding the shaft above the sleeve 7 is a cylinder 15 havingthreaded into its end a two-part bushing which surrounds the collarthrough which the pin 14 projects. The shaft 1 and sleeve 7 aremounted'for free rotation within the cylinder 15 and any suitabledriving mechanism may be applied to the shaft 1 to rotate the brushmembers in the bottle.

In order that the lower end of the shaft may center in the bottleproperly and freely rotate, I secure to the head 2 a friction disk 17 bymeansof a screw 18 on which the disk rotates and interposed between thedisk and the head 2 a series of anti-friction balls 19' upon which thedisk bears. When the de vice is pushed into the bottle, the frictiondisk 17 engages the bottom thereof and sticks to it while the shaft andits brush arms rotate upon the bearings 19. By-rotating the shaftrapidly after the device has been placed in the bottle, the sections 3',4. and 5, spread apart to operative position so as to bring the brushesin engagement with the sides,-top and bottom of the bottle.

Located in .the shaft 1 is an annular groove 20 in which'a spring 21carried by the cylinder is adapted to engage whereby excessive expansionof the members, 3, 4 and 5 is prevented. This excessive expansion mightstraighten out the top spring members 5 so as to carry their bristlesaway from the bottom.

The cylinder 15 is preferably covered with rubber 22 to prevent themetal from coming in contact with the glass bottle and in practice itmay be found to be necessary to use more'- than three rows of brushes. Itherefore desire to reserve this right and to make any such changes inthe structure shown herein as are found to be within the scope of theappended claims.

Having thus described the invention,

'what is claimed, is

1. The combinationwith a rotating shaft,

of a head fixed thereon, a member rotating with the shaft and slidablymounted thereon, brush members hingedly connected to the'head andsliding member, and a bearing head rotatably mounted on the fixed head.

2. The combination of a rotating shaft, of a head fixed thereon, a.sliding head on the shaft adapted to rotate therewith, brush membershingedly connected together and to said heads, and a bearing headrotatably mounted upon the fixed head.

3. The combination with a rotating shaft, of a head fixed thereon, abearing head rotatably mounted upon the fixed head, a head slidablymounted on said shaft, means for causing the rotation of the slid-ablymounted head with the/shaft, sectional brush members having theirsections connected together and to the heads, and means rotatablyconnected to the sliding head and to the shaft adapted to expand saidbrush sections.

l. The combination with a rotating shaft, of a head fixed thereon, afriction centering disk rotatably mounted upon the stationary head, ahead slidably mounted on the shaft, a key carried by the sliding headfor causing rotation thereof with the shaft, a .p1u-. rality of brusharms, each comprising apair of rigid sections, and a flexible sect-ion,means for connecting said sections together and to the heads wherebythey are adapted to be arranged parallel with the shaft for entranceinto a bottle neck, and means surrounding the shaft and rotatablyconnected with the sliding'head for expanding the brush arms in abottle.

5. In combination with a rotating shaft, collapsible brush membersconnectedto the shaft and adapted tojbe expanded upon rotation of theshaft, a cushioning member I rotatably mounted upon the shaft, and meansconnected to the shaft for preventing excessive expansion of the brushmembers.

In testimony whereof I atfix my signature in presence of two witnesses.
